Built comfortable, yet durable With a lightweight silicone facepiece, this reusable respirator is specifically designed to provide your employees with extended comfort. The adjustable head cradle and straps work together to offer an optimal fit, and the facepiece features our proprietary one-hand-touch Quick Latch mechanism that allows for easy drop-down after moving out of contaminated areas. A versatile choice The 3M™ 6500QL Series is compatible with a wide variety of NIOSH-approved 3M respirator cartridges and filters to help protect your workforce from certain particulates, gases and vapors. When used with 3M™ respirator filters and cartridges, this respirator may help provide respiratory protection at concentrations up to ten times the OSHA Permissible Exposure Limit (PEL). This half face respirator is also compatible with the 3M™ TR-600 and TR-800 powered air purifying systems (not approved with Dual Airline supplied air systems). Be proactive The 3M Respirator Selection Guide (3M.com/respiratorselector) may be used to help you select the proper respirators, cartridges, and filters for your work environment. Change your employee's 3M particulate filters anytime they are dirty, damaged, or difficult to breathe through. For gas/vapor cartridges, use the 3M Service Life software (3M.com/sls) to develop a cartridge change schedule.
